Physical properties of spray oil after plating of engraved round metal logo-A

Physical property analysis of Engraved Round Metal Logo after plating and oil spraying

Post-plating oil spraying is a common surface treatment process, mainly used to enhance the corrosion resistance, wear resistance, appearance and texture of metal logos and extend their service life. The following are the main effects and analyses of post plating oil spraying on physical properties:

1. Enhancement of corrosion resistance
   The role of the plating layer: the plating layer (such as nickel, chromium, zinc, etc.) itself has a certain degree of corrosion resistance, but there may be microporous or defective.
   The protective effect of oil spraying: oil spraying layer (such as epoxy resin, polyurethane, etc.) can fill the microporous plating layer, forming a dense protective film, effectively preventing the intrusion of moisture, oxygen and corrosive media, significantly improving the corrosion resistance.
   Application Scenario: Suitable for metal logos in outdoor or humid environments, such as automotive signs, outdoor equipment, etc.
2. Enhanced abrasion resistance
   Hardness of plating layer: The plating layer (e.g. hard chrome) itself has high hardness, but may be brittle.
   Cushioning effect of oil spraying: The oil spraying layer can provide some cushioning to reduce the direct abrasion of hard particles on the plating layer and prolong the service life.
   Application Scenario: Suitable for metal logos that require frequent contact or friction, such as signage for mechanical equipment.
3. Appearance texture improvement
   Lustre of plating: The plating layer can provide a metallic lustre, but it may be more single.
   Decorative nature of oil spraying: The oil spraying layer can provide a variety of colours and textures (e.g. matte, high-gloss, frosted, etc.) to enhance the visual effect.
   Application Scenario: Suitable for metal logos that require high decorativeness, such as consumer electronics, gifts, etc.
4. Fingerprint resistance and easy cleaning
   Surface properties of oil spraying: certain oil spraying materials (e.g. anti-fingerprint coatings) can reduce the adhesion of fingerprints and smudges and facilitate cleaning.
   Application Scenario: Suitable for metal logos that need to be kept clean, such as home appliances and mobile phone casings.
